IMPROVEMENT IN APPARATUS IE'ORMIXING HYDROG-EN AND AIR.

The Schedule referred to in these Lette rsv Patent and making part oi the same To all whom 'it may concern Be it known that I, DANIEL AsnwoRTH, of Wappingers Falls, in the county of Dutchess and State of New York, have invented a new and improved Hydro-` gen Gas and Air Mixer; and I do hereby declare that the following is a full, clear, and exact description thereof', which will enable others skilled in the vart to make and use the same, reference heilig had to the accompanying drawings forming part of this specification.

This invention relates to improvements in appa.-

tothe generation of it in closed vessels, for mixing with it the requisite quantity of atmospheric air, and for supplying a burner with the mixture, under the requisite pressure, to dispense with the blow-pipe in fusing metals; and

It consists in a-comhination with a gas-cylinder and an air-'cylinder of collapsible substance with fixed heads and movable partitions, the movable partitions of each being connected, so that the one belonging to the gascylinder being propelled will actuate the other, of a four-way cock for supplying and exhausting the gas, and mechanism for shifting the same, whereby the gas-cylinder and the said mechanism becomes a motor for operating the air-cylinder as a double-acting pump for forcing air into a receiver, into which the gas-cylinder exhausts, and from which the flame is supplied, the quantities of each being governed by the capacities of the respective cylinders, which are intended to be in about the proportion for one of gas and two of air. Y

Figure 3vis a plan view;

Figure 4 representsa face view of the stationary Figure vrepresents a face view of the movable or oscillating parts.

A represents the gas-cylinder, which, in this instance, is made of flexible India rubber, with metallie heads B, of sheet metal, fixed in suitable supports, and provided with a partition, G,'of wood or other substance, provided with arms D, fitted on rods E to slide hack and forth', also connected by rods F to a similar arm, G, of partition H in the air-cylinder I, of similar construction, to cause the two to move in unison. p

K is the supply-pipe leading from the gas-generator to the four-way valve L.

reference indicate corresponding the said valve to one end ofthe cylinder-A; and Nis a similar pipe leading to the other end.

O is the exhaust leading from the valve to the receiver P.

I to thereceiver. The air is let into the cylinder I through openings in the heads, which have inside valves which close them when the pressure is toward them.

The four-way valve oscillates on its horizontal axis and has an arm, E, connected by the rod S to the arm T, connected at U to a shaft, whereon is xed the cam-plate V, which is worked back and forth by a spring, W, attached to the free end of an arm, X, and bearing with considerable pressure on theface of the cam-plate through the medium of a friction-roller, y, attached to it.

The arm Xis connected by a bar, Z, to the moving partition C, `or to an arm thereon, and is vibrated by it. This cam-disk and the spring and the connections are so arranged that the moment the partition C arrives at the outer end of the cylinder the roller y will have` passed'so far beyond the point Vof the disk, at the greatest distance from 'its axis of motion, as to force it over on its axis one way or the other, as the ease may be, and vibrate the arms T R and the valve, thereby shifting it.

The arms E and T are .arranged for shifting the connection of the bar S to vary the movement ot' the valve as may be required.

In iig. 1 the partition C is represented as having arrived at the end of its movement to the left, and the spring and its roller as having passed the point V upward, and forced the cam-disk down, shifting the valve so as to open the exhaust from pipe M to O, and the induction from It to N. I

worked by the gasat the same speed of the other,

air will be taken in and mixed with the gas in the receiver in the exact proportion'of` the relative sizes of thecylinder, and that the receiver being connected with the burner, the latter will be supplied with a mixture Vof air and gas at the pressure due to that of the confined mixture in the receiver, which maybe regulated in any approved way.

a represents the supply-port, with which the pipe K connects;

b is the port for the pipe N;

c,.the poit for the pipe M; and

tl, the port for the pipe 0.

They oscillating part of the valve, ig. 5, has two curved passages, e f, one of which is, by the oscilla- Mis the induction and exhaust-pipe leading from tion of the said part, alternately brought to open the Q represents the air-pipes leading from thecylinder It will be seen that the air-pumping cylinder, being through the connections of the partitions H, that the passage from a to c and from c to d, and, in like manner, the other alternately opens the passage from a to b and from b to d, thereby'- supplying and exhausting the opposite ends of the cylinder alternately.

Having thus described my invention,

I claim as new and desire to secure by Letters Palt- V ent- 1. The combination of the gas and air-cylinder, pro vided with the reciprocating partitions connected together for joint action as described, of the four-way valve, the valve-actuating mechanism, the connectingpipes, and the receiver, all substantially as specified.

2. The combination with the reciprocating partition C and the valve-arm R of the vibrating arm X, the

spring W, cam-disk V, arm T, and rod S, substantially y GEO. W. MABEE, ALEX. F. ROBERTS.
